Figure 2

A plot of [(n-C6)*(MHs)]1/2 vs. [(MPs)*(n-C7)]1/2 for 900 crude oils; Fig. [2] in Mango (ref. 1). MHs = (2-MH + 3-MH); MPs = (2-MP + 3-MP). Concentrations are in wt.% total oil. The data are plotted as square root to constrain the scale to average concentrations. The line is the linear regression line: intercept = -0.068; slope = 1.01; r2 = 0.991. Mean for the ratio [(n-C6)*(MHs)]/[(MPs)*(n-C7)] = 0.75 ± 0.31s. Mean-centered s = 0.20.
